Inner covering for the connecting corridors between rail vehicles

ABSTRACT

The inner covering for the connecting corridors between cars of rail vehicles consists in each case of side wings, each of which consists of at least two independent frames (1, 2, 3) the spars of which are pivoted to each other at the corners, the frames being held in bottom and top telescopic guide rails (4). When the outermost vertical frame spars are fastened by hinges (8) to the car body or coupling frame, the inner covering can follow all movements which occur.

BACKGROUND OF THE INVENTION

The present invention relates to an inner covering for the connecting corridors between rail vehicles, i.e. corridors between the ends of two cars which are coupled to each other. Such corridors may be separable or not (in the case of compositions of trains which are not changed). The corridors have, in addition to the connection mechanism proper, an outer covering which is generally bellows-like and, for the covering said mechanical parts, frequently also an inner covering (for example also in bellows form, consisting of plastic).

It has recently been found that the known inner coverings are not fool proof against vandalism or, in the case of permanent embodiments, not fool proof against damage.

The purpose of the present invention was to create a stable inner covering for the connecting corridors of rail vehicles, i.e. stable side walls, which permit all actually occurring linear and rotatory movements without damage or dangerous openings.

This purpose is achieved with the new inner covering of the present invention.

SUMMARY OF THE INVENTION

In the solution of the invention, the movable frames which form side wings are connected to each other by the guide rails and covered by solid materials, i.e. extended, without substantial slot, up into the ceiling or bridge plates of the corridor.

Due to the construction of the side wings and, in particular, of the four articulated frames and the guide rails which extend into each other and connect the frames practically rigidly to each other:

longitudinal and transverse movements which take place between the ends of the cars can be taken up by the guide rails, which are of variable length;

vertical movements which take place between the ends of the cars are taken up by the guide rails and a parallelogram-like attachment of the frames;

turning movements of the ends of the cars around the vertical axis, leading to lengthwise movements in opposite directions of the side wings are taken up via the guide rails;

pitching movements between the ends of the cars are taken up by the guide rails and a parallelogram-like displacement of the frames; and

swaying movements between the ends of the cars are taken up by the guide rails and the articulation points of the frames, or by a certain play in these articulation points, as well as a twisting of the coverings.

The coverings or cover plates are preferably trapezoidal in shape, with the long side of the trapezoid fastened on the outer vertical spars of the frames. Resultant openings in the covering are covered preferably by triangular filler members which are fastened to the upper and lower frame spars.

BRIEF DESCRIPTION OF THE DRAWING

The invention will be explained in somewhat greater detail below, with reference to embodiments shown in the drawing, in which:

FIG. 1 shows, purely diagrammatically, the basic construction of a frame intended for the formation of a side wing;

FIG. 2 shows a side wing, formed of two frames, of the inner covering of a connecting corridor;

FIG. 3 shows a side wing, formed of three frames connected to each other by guide rails, the length of which wings can be reduced by the bringing together of the frames or increased by the pulling apart of the frames;

FIG. 4 shows the position of the frames, forming a side wing, with guide rails upon vertical movements between the ends of the cars, and

FIG. 5 shows the possible position of the frames forming a side wing upon pitching movements between the ends of the cars.

FIGS. 1 and 2 illustrate diagrammatically the basic construction of a side wing of an inner covering for a connecting corridor between cars of rail vehicles. Articulated highway vehicles (articulated buses) would also correspond to such a rail vehicle.

The entire inner covering of the connecting corridor consists of four side wings, i.e. two per side, in the case of a separable connecting corridor arrangement with coupling frames, or of two side wings, i.e. one per side, in the case of a non-separable corridor arrangement.

One side wing consists of two or more independent holding frames which are connected to each other by upper and lower guide rails and possibly additional centering elements.

FIG. 1 illustrates the construction of an individual element for a side wing, consisting of a holding frame of vertical spars 1 and horizontal spars 2, 3. The horizontal spars 2, 3 are guided in guide rails 4 and all the spars are connected to each other by pivots 7 at their corners. The pivots produce from the frame at least one four-bar arch or four-bar frame, which can change in a parallelogram-like manner.

As shown in FIG. 2, the side wing is arranged with its outermost vertical spars 1 swingable by hinges 8 on the car body and coupling frame or on one and the other car bodies, around the longitudinal axis of the vertical spar 1.

The guide rails 4 which are guided telescopically one within the other and which hold and guide the frames vertically, displaceable relative to each other, are pivoted, for instance, at their outermost ends also to the ends of the outermost spars 1.

On the outermost vertical spars 1 there are also fastened rigid cover plates 6, preferably of trapezoidal shape, so that no interferences can occur upon given movements of the individual frames. The openings between cover plates 6 and frames which are thereby produced are covered by so-called filler members 5, which are fastened in suitable manner in the horizontal frame spars 2, 3.

Due to the pivots 7 at the corners of the frame, the frame can be displaced in the manner of a parallelogram and at the same time, if necessary, twisted (due to some play in the joints).

FIG. 3 shows a side wing formed of three frames. The guide rails 4 of the frames are guided in drawer-like or telescopic manner one within the other. In the case of three frames, an additional centering or guide device in the form of a scissors mechanism 9 is provided, as shown, it seeing to it that the central frame moves in predetermined manner with respect to the outer frames.

FIGS. 4 and 5 illustrate, in the case of side wings of two and three frame parts respectively, how the entire assembly can shift easily under certain external forces (movements in accordance with FIG. 4 can also be combined furthermore with those in accordance with FIG. 5).

Inner coverings of the type described above are simple to construct and manufacture. Their functioning is practically trouble-proof, and cover plates which have possibly been damaged can be replaced easily and rapidly.
